Ryan paid $5,560 in 2009.
Let's solve the problem using the given information: Amount paid in 2010 by Ryan = $1,112 Amount paid in 2010 is 80% less than the amount paid in 2009.
So, the amount paid in 2009 can be calculated as follows: Let x be the amount paid by Ryan in 2009.
Then we can write, $1,112 = x - 0.8x Simplifying this expression, we get:$1,112 = 0.2x Dividing both sides of the equation by 0.2, we get: x = $5,560
Therefore, Ryan paid $5,560 in 2009. I hope this helps.

Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.
Step 1: m = StartFraction 13 minus 25 Over negative 4 minus (negative 7) EndFraction = StartFraction negative 12 Over 3 EndFraction = negative 4. Step 2: y = negative 4 x + b. 25 = negative 4 (negative 7) + b. 25 = 28 + b. 25 minus 28 = 28 + b minus 28. b = negative 3. Step 3: y = negative 3 x minus 4
What was Brooke’s error?
She found the incorrect slope in step 1.
She mixed up the x- and y-coordinates when she plugged in the point in step 2.
She found the incorrect y-intercept in step 2.
She mixed up the slope and y-intercept when she wrote the equation in step 3
Answer:
she mixed up the slope and y- intercept in step 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
she correctly calculated the slope as m = - 4 and the y- intercept b = - 3
thus equation she should have is
y = - 4x - 3
Brooke's error was that she found the incorrect slope in step 1.
The slope formula is: m = (y₂ - y₁) / (x₂ - x₁)
Using the given points: m = (13 - 25) / (-4 - (-7)) m = -12 / 3 m = -4
So, the slope is -4, not -12/3 as Brooke calculated in step 1.
The correct equation for the line passing through the points (-7, 25) and (-4, 13) is: y = -4x - 3 (as found in step 3)

seven more than a certain number is nin nine less than twice the number. find the number.
Answer:
number is 16
Step-by-step explanation:
let n be the number , then 7 more than the number is n + 7 and 9 less than twice the number is 2n - 9
equating the 2 expressions
2n - 9 = n + 7 ( subtract n from both sides )
n - 9 = 7 ( add 9 to both sides )
n = 16
the required number is 16
The answer is:
n = 16Work/explanation:
Let's call the number n.
Seven more than n = n + 7
Nine less than twice n = 2n - 9
Put the expressions together : n + 7 = 2n - 9
Now, we have an equation that we can solve for n.
First, flop the equation
2n - 9 = n + 7
Subtract n from each side
n - 9 = 7
Add 9 to each side
n = 16
Therefore, n = 16.Es el conjunto de deshielo determinante de la matriz x 2

Which complex number is equivalent to this expression? 1/3(6+3¡)-2/3(6-12¡)
So, the complex number equivalent to the given expression is 0 + 9i, which can also be written as 9i.
To simplify the expression 1/3(6 + 3i) - 2/3(6 - 12i), we can perform the necessary calculations.
First, let's simplify each term separately:
1/3(6 + 3i) = 2 + i (divide each term by 3)
2/3(6 - 12i) = 4 - 8i (divide each term by 3)
Now, let's substitute these simplified terms back into the original expression:
2 + i - (4 - 8i)
When subtracting complex numbers, we distribute the negative sign:
2 + i - 4 + 8i
Combine like terms:
(-2 + 2) + (i + 8i) = 0 + 9i
The expression 1/3(6 + 3i) - 2/3(6 - 12i) simplifies to 9i.
We can make the necessary computations to simplify the statement 1/3(6 + 3i) - 2/3(6 - 12i).
Let's first simplify each phrase individually:
Divide each term by 3 to get 1/3(6 + 3i) = 2 + i.
Divide each term by 3 to get 2/3(6 - 12i) = 4 - 8i.
Let's now add these abbreviated terms back into the original phrase:
2 + i - (4 - 8i)
Distributing the negative sign while subtracting complex numbers is as follows:
2 + i - 4 + 8i
combining similar terms
(-2 + 2) + (i + 8i) = 0 + 9i
A simplified version of the phrase 1/3(6 + 3i) - 2/3(6 - 12i) is 9i.

Please calculate the volume of a solid oblique pyramid with a triangular base, given that the base has a length of 8 inches and a height of 6 inches, and the height of the pyramid is 10 inches. Round your answer to the nearest cubic inch.
Answer: 74
Step-by-step explanation:
The volume of the pyramid can be found using the formula:
Volume = (1/3) x Base Area x Height
To find the base area, we need to find the area of the triangular base. The area of a triangle can be found using the formula:
Area = (1/2) x Base x Height
Substituting the given values, we have:
Area = (1/2) x 8 x 6 = 24 square inches
To find the height of the pyramid, we can use the Pythagorean theorem. The slant height and one-half of the base form a right triangle, so we have:
Height^2 = (Slant Height)^2 - (1/2 x Base)^2
Height^2 = 10^2 - 4^2
Height^2 = 84
Height = √84 ≈ 9.165 inches
Now we can substitute the values into the formula for the volume:
Volume = (1/3) x Base Area x Height
Volume = (1/3) x 24 x 9.165
Volume ≈ 73.96 cubic inches
Therefore, the volume of the pyramid is approximately 73.96 cubic inches.Step-by-step explanation:

Let p(x) = a1x^2 + b1x +c1 and q(x) = a2x^2 + b2x + c2 be polynomials in P2. Define an inner product in P2 as follows {p,q} = 5a1a2 + 4b1b2 + 3c1c2.
Given p(x) =5x^2 + (-1)x + (-3) and q(x) = 2x^2 + (4)x +(-3). Evaluate the following expressions
1. p(x) - q(x) = 3x^2 - 5x
2. {p - q, p-q} = 145
3. llp-qll = sqrt({p-q,p-q}) = sqrt(145)
For part 1, I know the answer and how to get it.
For part 2, I know the answer but I'm not sure how to get to it
Answer:
Step-by-step explanation:
To evaluate the expression {p - q, p - q}, which represents the inner product of the polynomial (p - q) with itself, you can follow these steps:
Given p(x) = 5x^2 - x - 3 and q(x) = 2x^2 + 4x - 3.
Subtract q(x) from p(x) to get (p - q):
(p - q)(x) = (5x^2 - x - 3) - (2x^2 + 4x - 3)
= 5x^2 - x - 3 - 2x^2 - 4x + 3
= (5x^2 - 2x^2) + (-x - 4x) + (-3 + 3)
= 3x^2 - 5x
Now, calculate the inner product of (p - q) with itself using the given inner product formula:
{p - q, p - q} = 5(a1)(a2) + 4(b1)(b2) + 3(c1)(c2)
= 5(3)(3) + 4(-5)(-5) + 3(0)(0)
= 45 + 100 + 0
= 145
Therefore, the value of {p - q, p - q} is 145.

A man goes 10m North and turns left and covers 6m. He again turns left and walks 5m. Which direction is he in from starting point?
The man is in the south direction from the starting point.
Let's visualize the movements of the man step by step:
The man starts by going 10 meters north.
He then turns left (which means he is now facing west) and covers 6 meters in that direction.
Next, he turns left again (which means he is now facing south) and walks 5 meters.
To determine the final direction of the man from the starting point, we can consider the net effect of his movements.
Starting from the north, he moved 10 meters in that direction. Then, he turned left twice, which corresponds to a 180-degree turn, effectively changing his direction by 180 degrees.
Since he initially faced north and then made a 180-degree turn, he is now facing south. Therefore, the direction he is in from the starting point is "south."

what is (0.3)0 in binominal distribution
Answer:
When p, the probability of success, is zero in a binomial distribution, the probability of getting exactly k successes in n trials is also zero for all values of k except when k is zero (i.e., when there are no successes).
So, in the case of (0.3)^0, the result would be 1, because any number raised to the power of 0 is equal to 1. Therefore, the probability of getting zero successes in a binomial distribution when the probability of success is 0.3 is 1.
–5 < 2x – 1 < 3 solve?? help aap
Answer:
Step-by-step explanation:
To solve the inequality -5 < 2x - 1 < 3, we will break it down into two separate inequalities and solve each one individually.
First, let's solve the left inequality:
-5 < 2x - 1
Add 1 to both sides:
-5 + 1 < 2x - 1 + 1
-4 < 2x
Divide both sides by 2 (remembering to reverse the inequality when dividing by a negative number):
-4/2 < 2x/2
-2 < x
Now, let's solve the right inequality:
2x - 1 < 3
Add 1 to both sides:
2x - 1 + 1 < 3 + 1
2x < 4
Divide both sides by 2:
2x/2 < 4/2
x < 2
So, the solutions to the inequalities are:
-2 < x < 2
This means that x is greater than -2 and less than 2.

Answer:
-5/4
Step-by-step explanation:
Let [tex](x_1,y_1)=(-4,4)[/tex] and [tex](x_2,y_2)=(0,-1)[/tex]. The slope of the line would be:
[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{-1-4}{0-(-4)}=\frac{-5}{4}=-\frac{5}{4}[/tex]
Answer: -5/4
Step-by-step explanation:
To find the slope between two points, you can use the formula:
Slope = (y2 - y1)/(x2 - x1)
Using the points (0, -1) and (-4, 4), we can substitute the coordinates into the formula:
slope = (4 - (-1))/(-4 - 0)
slope = (4 + 1)/(-4)
slope = 5/-4
Therefore, the slope between the two points is -5/4.
Point B is on line segment AC. Given AC = 2x + 7, BC = x, and
AB= 5x9, determine the numerical length of AB.
Answer:
Step-by-step explanation:
To determine the length of AB, we need to find the value of x.
We are given that AC = 2x + 7, BC = x, and AB = 5x + 9.
Since B is on the line segment AC, the sum of lengths AB and BC should equal the length of AC. Therefore, we can set up the equation:
AB + BC = AC
Substituting the given values, we have:
(5x + 9) + x = 2x + 7
Simplifying the equation:
6x + 9 = 2x + 7
Bringing like terms to one side:
6x - 2x = 7 - 9
4x = -2
Dividing both sides by 4:
x = -2/4
Simplifying:
x = -1/2
Now that we have the value of x, we can substitute it back into the expression for AB to find its numerical length:
AB = 5x + 9 = 5(-1/2) + 9 = -5/2 + 9 = (18 - 5)/2 = 13/2 = 6.5
Therefore, the numerical length of AB is 6.5.

Generate a continuous and differentiable function f(x) with the following properties:
f(x) is decreasing at x=−5
f(x) has a local minimum at x=−3
f(x) has a local maximum at x=3
The function f(x) = -0.5(x + 5)³(x + 3)(x - 3) satisfies the specified conditions of decreasing at x = -5, having a local minimum at x = -3, and a local maximum at x = 3.
How to Generate a Continuous and Differentiable Function?One possible function that satisfies the given properties is:
f(x) = -0.5(x + 5)³(x + 3)(x - 3)
Check as follows:
Decreasing at x = -5:
Taking the derivative of f(x) and evaluating it at x = -5, we have:
f'(x) = -1.5(x + 5)²(x + 3)(x - 3) - 0.5(x + 5)³
f'(-5) = -1.5(0)²(-2)(-8) - 0.5(0)³ = 0 - 0 = 0
The derivative is zero at x = -5, therefore the function has a critical point at that location. To check if it is a maximum or minimum, we can examine the second derivative.
Taking the second derivative:
f''(x) = -3(x + 5)(x + 3)(x - 3) - 3(x + 5)²(x - 3)
f''(-5) = -3(0)(-2)(-8) - 3(0)²(-8) = 0 - 0 = 0
The second derivative is also zero at x = -5. However, since the first derivative is negative for x < -5 and positive for x > -5, this means that f(x) is decreasing at x = -5.
Local minimum at x = -3:
To check if f(x) has a local minimum at x = -3, we can examine the first and second derivatives at that point.
Taking the first derivative:
f'(-3) = -1.5(2)²(0)(-6) - 0.5(2)³ = 0
The first derivative is zero at x = -3, indicating a critical point.
Taking the second derivative:
f''(-3) = -3(2)(0)(-6) - 3(2)²(-6) = 0 - 72 = -72
Since the second derivative is negative at x = -3, this confirms the presence of a local minimum.
Local maximum at x = 3:
To check if f(x) has a local maximum at x = 3, we can again examine the first and second derivatives at that point.
Taking the first derivative:
f'(3) = -1.5(8)²(6)(0) - 0.5(8)³ = 0
The first derivative is zero at x = 3, indicating a critical point.
Taking the second derivative:
f''(3) = -3(8)(6)(0) - 3(8)²(0) = 0 - 0 = 0
The second derivative is zero at x = 3, indicating that the test is inconclusive. However, since the first derivative is positive for x < 3 and negative for x > 3, this means that f(x) is decreasing at x = 3.
Therefore, the function f(x) = -0.5(x + 5)³(x + 3)(x - 3) satisfies all the given conditions.

Vertical Asymptote Vertical asymptotes occur when a function approaches infinity or negative infinity at a specific value of x. This can occur in a rational function where there is a division by zero.
A vertical asymptote is found when the denominator of the rational function becomes zero. Since division by zero is undefined, it means that the rational function approaches infinity or negative infinity.
The equation of the vertical asymptote is x = a where a is the value that makes the denominator zero.
Horizontal AsymptoteA horizontal asymptote occurs when a function approaches a constant value (y) as x approaches infinity or negative infinity. A horizontal asymptote occurs when the degree of the numerator and denominator is the same.
The horizontal asymptote is found by comparing the degrees of the numerator and denominator and dividing the leading coefficient of the numerator by the leading coefficient of the denominator.3.1 Equation of the asymptotes of the equation of the vertical asymptote is x=1.
The degree of the numerator is less than the degree of the denominator. Therefore, the horizontal asymptote is y=0The equation of the horizontal asymptote is y=0.3.2 X-intercept of fTo find the x-intercept of f, set y=0.f(x) = 0= 1/(x-1) -2Add 2 to both sides2 = 1/(x-1)Take the reciprocal of both sides of the equation.1/2 = (x-1)x-1 = 2x = 3Hence, the x-intercept of the function is (3,0)

[tex] \frac{1}{( - 7)^{4} } [/tex]
Answer:
[tex](-7)^-^4=\frac{1}{(-7)^4}[/tex]
Step-by-step explanation:
The user aswati already wrote the correct answer, but I wanted to help explain why their answer is correct so that you'll understand.
According to the negative exponent rule, when a base (let's call it m) is raised to a negative exponent (let's call it n), we rewrite it as a fraction where the numerator is 1 and the denominator is the base raised to the same exponent turned positive.
Thus, the negative exponent rule is given as:
[tex]b^-^n=\frac{1}{b^n}[/tex]
Thus, [tex](-7)^-^4[/tex] becomes [tex]\frac{1}{(-7)^4}[/tex]

Determine the equation of the hyperbola with foci... 100pts
Answer:
[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]
Step-by-step explanation:
To write the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8), we first need to determine the orientation of the hyperbola.
As the y-values of the foci are the same, the foci are located horizontally from the center of the hyperbola, and therefore the hyperbola is horizontal (opening left and right).
The standard equation for a horizontal hyperbola is:
[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]
where:
center = (h, k)vertices = (h±a, k)foci = (h±c, k) where c² = a² + b²The center of a hyperbola is the midpoint of the vertices.
Given that the vertices are (-1, -8) and (-11, -8), we can use the midpoint formula to find the coordinates of the center:
[tex](h,k)=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)[/tex]
[tex](h, k)=\left(\dfrac{-1-11}{2},\dfrac{-8-8}{2}\right)[/tex]
[tex](h, k)=\left(-6,-8\right)[/tex]
The value of "a" is the distance between the center of the hyperbola and each vertex. To find the value of a, calculate the distance between the x-coordinates:
[tex]a=-1-(-6)=5[/tex]
[tex]a=-6-(-11)=5[/tex]
The value of "c" is the distance between the center of the hyperbola and each focus. Given that the foci are (7, -8) and (-19, -8), and the center is (-6, -8), to find the value of c, calculate the distance between the x-coordinates:
[tex]c = 7-(-6)=13[/tex]
[tex]c = -6-(-19)=13[/tex]
Now we have determined the values of a and c, we can use c² = a² + b² to find the value of b:
[tex]c^2 = a^2 + b^2[/tex]
[tex]13^2 = 5^2 + b^2[/tex]
[tex]169 = 25 + b^2[/tex]
[tex]b^2=144[/tex]
[tex]b=12[/tex]
Finally, substitute the found values of a, b, h and k into the standard equation of a hyperbola:
[tex]\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1[/tex]
[tex]\dfrac{(x-(-6))^2}{5^2}-\dfrac{(y-(-8))^2}{12^2}=1[/tex]
[tex]\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1[/tex]
Therefore, the equation of the hyperbola with foci (7, -8) and (-19, -8), and vertices (-1, -8) and (-11, -8) is:
[tex]\boxed{\dfrac{(x+6)^2}{25}-\dfrac{(y+8)^2}{144}=1}[/tex]

I need help understanding how to format this:
f(x)-4
f(x)=2x+1
an example of another question for it (if you're not sure what im asking), another question was to answer this:
f(4)
f(x)=2x+1
f(4)=2(4)+1
this one is easy to get, but i'm not too sure how to put it on the first one...
Answer:
Step-by-step explanation:
To format and solve the equation "f(x) - 4" with the given function "f(x) = 2x + 1," we substitute the function into the equation and solve for x. Here's how it can be done:
f(x) - 4 = 2x + 1 - 4
Simplifying further:
f(x) - 4 = 2x - 3
To answer the question "f(4)" using the function f(x) = 2x + 1, we substitute x = 4 into the function:
f(4) = 2(4) + 1
Simplifying further:
f(4) = 8 + 1
f(4) = 9
Therefore, the value of f(4) is 9 when using the function f(x) = 2x + 1.
